Brief Summary:
Young children rely on their foods and drinks for the nutrients they need to grow, like energy, protein, vitamins, and minerals. In addition to nutrients, there are substances in fruits, vegetables, milk and formula, called phytochemicals, that can support health. While researchers know more about the role of phytochemicals in adult health, researchers know surprisingly little about how phytochemicals can support health in young children. One group of phytochemicals are called the carotenoids. Carotenoids are responsible for the red, orange, and yellow colors in some fruits and vegetables. In adults, carotenoids can support visual function. Researchers also know that measuring levels of carotenoids in the blood or optically in the skin, can serve as an indirect measurement of what child and adults eat.
The purpose of this study is to determine how a child's usual intake of carotenoids is related to their visual development and their blood and skin levels of carotenoids. The study involves 6 visits. For each visit, we will ask about the child's recent diet, will measure their body size, collect a blood sample, collect optical measurements of their skin, and will test how sharp their vision is.

Detailed Description:
Early life nutrition is recognized as key determinant of short- and long-term health. However, a lack of objective, reliable, and valid methods to determine what exactly children makes it difficult to carefully study nutrition in infants and toddlers.
Carotenoids are fat-soluble pigments found primarily in fruits and vegetables (F\&Vs) that support healthy functioning. Carotenoids support vitamin A requirements, reduce inflammation and cancer risk, and support cognitive, visual, and cardiovascular health. Since carotenoids are colorful, researchers can easily measure them in blood and tissues using color-measuring devices. Blood carotenoid concentrations are used as biomarkers of adult F\&V intake. Advances in carotenoid measurement technologies may make carotenoid biomarker measures in children more feasible. However, the precision and accuracy of these biomarkers in children is not as well understood.
With better measures of carotenoid intake comes the opportunity to understand how carotenoid intake relates to children's health. A high priority area to investigate in this young children is whether dietary carotenoids are associated with visual function. Lutein and zeaxanthin, carotenoids that accumulate in the back of the eye (macula), are associated with visual contrast sensitivity in children and adults, a visual function which may support children's interactions with their environments, but this association has not been sufficiently studied in healthy infants and toddlers. In this study, the investigators will define in infants and toddlers 1) the rigorous validation of a skin carotenoid biomarker of dietary intake and 2) the associations between carotenoid intake and visual function.
